One of the things scientists do after investigating is to put things into groups. Scientists classify things. So, all things made of metal go into a group called metals. Some of those metals may be bendier or shinier than others, but they are still all metals. In science at school you will have put things into big groups, like plants, animals, metals, plastics. You can also put things into groups after investigating their properties: are things stretchy, transparent, or hard?
